1. CONTRAST OF MISCELLANEOUS PARTS
NOTES:
• Parts marked by "NSPnare generally unavailable because they are not in our Master Spare Parts List.
• The ,6 mark found on some componentparts indicates the importance of the safety factor of the part. Therefore, when replacing,
be sure to use parts of identical designation.
• Parts marked by"@" are not always kept in stock. Their delivery time may be longer than upual or they may be unavailable.
• When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex . 1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by]= 5% ,
and K = 10%).
